PASTlNG-BOX.

SPECIFICATION forming part of Letters Patent'No. 786,975, dated April 11, 1905.

Application filed February 27, 1904. Serial No. 195,666.

To all whom it may concern.-

Be it known that I, HERBERT G. LA SoR, a citizen of the United States, and a resident of the city of Washington, in the District of Columbia, have invented a new and useful Improvement in Pasting-Boxes, of which the following is a specification.

My invention relates to an improvement to be set to deposit the requisite amount of paste upon the uppermost sheet, the hopper being mounted on piling-bars in such a manner that it is supported upon the sheets and descends as the uppermost sheets are successively withdrawn, depositing the paste upon the end of the sheet.

My present invention also comprises means for regulating the size of the opening to the width of sheet; and itfurther consists in certain novel features of construction and combinations of parts, which will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side view, Fig. 2 is a plan view, Fig. 3 is a View in perspective, Fig. 4 is a detached view in perspective, of the regulating-valve, and Fig. 5 is a section on line 5 5 of Fig. 2.

A represents the base of the pasting-box, and 1 1 are piling-bars screwed or otherwise secured to the base at the forward end thereof. These piling-bars serve a double function, the first of which is to aflord support for the hopper and the second a means against which the edges of the sheets are piled and from which function they derive their name. Two only of these piling-bars are shown, although it is obvious that more might be employed.

B is the hopper, and it comprises the ends 2 and 3, the front late4, and the sloping bottom 5, and the -ower edges of the front and bottom terminate a suitable distance from each other to afford an outlet for the paste contained within the hopper. This outlet or mouth 6 has a valve 7 therein which controls it and determines the size of the outlet, and the lower edge of the bottom late is concentric with the axis 8 of the va ve, as shown at 9, whereby to fit the curved surface 10 of the valve, and thereby "prevent leakage at that oint, while the rear edge of the lower end of the front plate is ground to accurately fit and parallel the forward edge of the curved valve, so that the size of the outlet may be regulated accordin to the quantity of aste or width of pasted area to the sheet. s a simple means for regulating the size of the opening the axis of the valve is provided at one end with an arm 22, and a pair of set screws 11 and 12, turning in threaded holes 13 13 in lugs 14 14 on the end plate 2, abut against the upper and lower surfaces of this arm, whereby it is simply a matter of their manipulation to adjust and lock the valve. The front plate is provided with holes formed in the ears 15 15, (see Figs. 2 and 3,) which receive the piling-bars, whereby the hopper is mounted thereon.

As a means for supporting the hopper in an elevated position when replenishing thehopper with paste or the machine with paper or, in fact, when not actually performing the pasting function, the spring-actuated pins 16 16 are arranged to slide in holes provided for them in the front plate and to drop into notches 18 18 when the hopper is elevated to a point where the pins reach said notches. To lower the hopper, the pins are pulled outward against the action of the spring, and the hopper is permitted to rest upon the pile of sheets.

To adjust the length of opening to the width of the sheets being operated upon, strippers 19 19 are provided, these being arranged to slide or beadjusted in and out upon the dovetailed guides 20 20, located at the lower corners of the front plate 4. The rear ends of the strippers are concentric with the curvature of the valve, and they are adapted to rest upon the edges of the sheets or at the edges .of the sheets, whereby to close the opening at that point, or, in other vsiprds, to adjust its length to the width of the s eets.

An additional piling-bar 21 may be adj ustably connected with one of the side edges of the base as an additional means for gaging the paper, this being set in alinement with the inner edge of one of the strippers, where by to determine the position of the sheets upon the base.

From the foregoing it will be understood that the sheets to be pasted are placed upon the base against the several piling-bars, the hopper is supplied with paste, and the valve adjusted to suit the requirements, as well as the strippers set to the width of the sheets. Then the hopper is lowered until it rests upon the paper, whereupon the sheets are drawn out one at a time, the hopper following them down as fast as the sheets are removed and always resting upon the edge of the upper most sheet.

It is evident that a great variety of uses are open to a device of this character and also that many slight changes might be made in the form and arrangement of the several parts described without departure from the spirit and scope of my invention as defined by the claims, and hence I do not wish to limit myself to the exact construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a suitable base having vertical guides, a paste-receptacle slidably mounted thereon, the paste-receptacle provided with a permanent slotted opening, of means for regulating the length of the slot, an oscillatory curved device for regulating the width of the slot, the means for regulating the length of the slot comprising dovetailed guides located on the paste-receptacle, and strippers carried by the guides, the strippers provided with grooves engaging the guides, the rear ends of the strippers formed concentric with and frictionally engaging the curved oscillatory device, the strippers movable lengthwise of the slot.

2. The combination with a suitable base, having vertical guides, a paste-receptacle slidably mounted on the guides and provided with a permanent slotted opening, of an oscillatory member for regulating the width of the opening, the member comprising a concavo-convex gate journaled within the pastereceptacle, the lower edge of the gate located in horizontal alinement with one edge of the slotted opening, an arm rigidly secured to one of the journals, lugs mounted on the receptacle and set-screws carried by the lugs and adapted to engage the arm from opposite directions.

3. In a pasting-box, the combination with a suitable base for receiving the sheets of material, of a plurality of piling-bars extending above the base, a paste-holding receptacle slidably mounted on the bars, and pro vided with a dischargeoutlet, the receptacle normally resting and supported upon the uppermost sheet, the bars provided withnotches or recesses, and means carried by the pasteholding receptacle adapted to be rcmovably received in the notches or recesses, to retain the receptacle in elevated position above the sheets.

4. In a pasting-box, the combination with. a base for receiving the sheets of material to be pasted, of a suitably-mounted )astehold ing receptacle normally freely slidable toward and from the base, the receptacle provided with a paste-discharging outlet, means for closing this outlet, and releasable means for retaining the receptacle in elevated position above the sheets.

5. In a pastingboX, the combination with a base upon which are piled sheets of material to be pasted, of a bar carried by the base and provided with a notch, a paste-holding receptacle slidably mounted on the bar, and provided with a discharge-outlet, means for closing the outlet and a spring-actuated pin carried by the receptacle and adapted to engage the notoh to retain the receptacle in elevated position above the piled sheets.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
